APPARATUS FOR CONSTRUCTION OF CEMENT BUILDINGS.

To all whom/it may concern:

Be it known that I, JACOB M. THoMPsoN, a citizen of the United States, residing at Fond du Lac, in the county of Fond du Lac and State of l/Visconsin, have invented certain new and useful Improvements in Apparatus for Construction of Cement Buildings; and I do declare the following to be a full, clear, and exact.description of the invention, such as will enable others skilled in the art'to which it appertains to make and use the same.

This invention relates to improvements in means employed in the construction of the walls and partitions of buildings where cement or artificial stone is used.

The object of the invention is to provide apparatus whereby not only will the results be satisfactory but the building operations may be so simplified and each step so economically and expeditiously performed that the ultimate cost will be less than that of walls of equal durability when constructed of other materials. with other apparatus and in accordance with other methods.

Another object is to provide apparatus for constructing a wall having clean unobstructed air spaces extending from top to bottom thereof, thereby avoiding all danger of frost or dampness jumping across said spaces, and which may be operated by unskilled labor. 1

' With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and claimed. F

In the accompanying drawings Figure 1 represents a side elevation of a partially completed wall showing this improved apparatus applied; Fig. 2 is a horizontal section taken on the line 22 of Fig. 1; Fig. 3 is a vertical section taken on the line 33 of Fig. 1; Fig. 4 is an enlarged detail plan view of a portion of the mold with parts broken out and in section; Fig. 5 is a vertical section taken on the line 5-5 of Fig. 4,

.and Fig. 6 is a transverse section taken on Specification of Letters Patent.

rials used for like purposes, due largely to Patented ar. 2, 1915.

Application filed September 21, 1914. Serial No. 862,809. r

This invention is designed to overcome the difficulties, heretofore encountered, by a proper combination of means or mechanism which aids in the performance of the work whereby the Work may be materially expedited and simplified and the results show a degree of strength and regularity of appearance not before attained without the employment of expensive skilled labor.

In the embodiment illustrated a frag ment of a wall is shown in section in Fig. 3 in a substantially completed condition and it will be seen that it consists of inner and outer facings or sections A of cement or artificial stone separated by a space B which extends from the top to the bottom of said wall and is unobstructed throughout.

The facings A may be of any desired thickness and one thicker than the other if desired, or both .of the same thickness. These facings A are formed by pouring the ingredients (cement, sand, etc.) previously mixed and tempered to the proper degree, into suitable molds which are arranged side by side and spaced from each other to pr'ovide for the air space B between the facings. The mold for forming this wall is here shown composed of two chambers 1 and 2 arranged side by side and spaced apart, the walls 3 of said chambers being composed of sheet metal which is pressed around. an angle iron frame which consists of an upper member 4 L-shaped in cross section and a similar bottom or lower member 5, said sheet metal walls 3 serving to connect these upper and lower members of the mold.

The two sections of the mold which constitute the chambers 1 and 2 are connected with each other'by uprights 6 and 7 detachably connected with said sections by removable pins 8 and these uprights are preferably constructed of angle irons U-shaped .in cross section as shown in Fig. 6 and the The upper and lower members 4 and 50f each mold section are shown connected at their ends by angle irons 11 which are preferably welded to said upper and lower members at the corners of the side members of the mold sections, see Fig, 4. r

The laterally extending flanges ofthe upper and lower members of the mold sections project outwardly as shown in Fig. 3

and are designed to engage supports formed on suitable clamps soonto be described and which support said molds in operative position without the use of any other sup porting means.

The clamps which hold the molds po-.

sition are here shown, each formedof uprights 12 and 13 having inturned lower ends 14 on which are mounted clamping plates having faces 15 for engaging the outer faces of the completed wall sections as is shown clearly in Figs. 1 and 3. These uprights 12 and 13 are made of any suitable or desired length and are connected at their upper ends by a sectional rod 16 provided with a turn buckle 17 for adjusting the length thereof and'thus moving the clamping ends of the members 12"and 13 toward or away from each other as may be desired when applying or removing the clamp from the wall with which itis to be used. These members 12 and .13 are pivotallyconnected together near their upper ends by bars 18 and 19 which are fixedly secured at one end to said members 12 and 13 respectively,

preferably by means of removable pins 8" I and which have their inner meeting ends ends at any desired point, preferably, midpivotally connected as shown at 20.

Mold supporting brackets 21 and 22 [are shown secured to the inner faces of the members 12 and 13 intermediately' of their way of said ends and these supports are here shown in the form of angle-irons L-sha'ped in cross section with their laterally extend- 'ing flanges 21 and 22 projecting inwardly to receive and support the lower members I,

of the outer walls of the mold sections 1 and 2 as is shown cle'arly in Fig. 3.

' In the use of this apparatus the lower or bottom courses are sections of the wall having been formed on' the supportingsurface on which the wall is to be built, in the usual manner, said mold is removed after the ocment is set and when said wall portion has hardened, the mold supporting clamps are applied thereto by ehgaging the clamping faces 15 thereof with the outer faces of the completed portion of the wall.

curely clamped in engagement therewith by expandingor forcing apart the upper ends of the members 12 and 13 by turning the pivotal connection'of said members and thus fa cings A as shown in Fig. 3 and are sesaid clamp will be securely mounted on the When positioning these clamps on said wall they are soarranged that the brackets 21 and: 22 thereof will be positioned adjacent the upper. edges of the completed wall sections as shown clearlyin Fig. 3 ready to receive and support the lowermembers of the outer walls of the mold. lVhen said mold has tion of the facings A and they are then ready to receive more cement which is tamped into the mold sections and held therein until it has sufiiciently hardened to permit the removal of the mold. To remove the mold, the buckle 10 is turned to release the side members thereof from the material contained therein and the mold may be then removed and is ready for use again when the cement facings have. become sufficiently hardened to supportthe clamps on which the moldis to be mounted.

From the above construction it will be obvious that this apparatus provides for great economy of construtatiomrendermg 1t possible for a man of small means to construct a building for himself without employing skilled labor and that the apparatus is so simple that it can be made and marketed at a very low cost.

It will also be observed that a wall constructed by this apparatus will provideair spaces B extending throughout the height thereof without any obstructions from top to bottom which is very desirable to a'v o1d any danger of dampness or frost passing from the outer to the inner facmgs, thus iend'ering the building formed by said walls I laim as .my invention: 3

1. A mold comprising a plurality of laterally spaced parallel. plates,'uprights secured to the outermost plates and extending above the tops thereof, adjustable means connecting the uprights'on opposite sides at the mold and pivotally connected members attached to the innermost plates and to said uprights, said members extending transversely across the chambers formed by' the:

parallel plates.

2. A mold comprising a plurality of laterally spaced parallel plates, uprights secured to the outermost plates and extending above thetops thereof, adjustable means connectingthe uprights on opposite sides of the mold, uprights secured to the innermost plates and having laterally extending pivotally connected arms at their upper ends,

said arms being also secured to'the first mentioned uprights, and extending transversely relatively to the mold.

3. A mold comprising a plurality of laterally spaced parallel plates, uprights secured to the outermost plates and extending above the tops thereof, adjustable means connecting the uprights on opposite sides of the mold, uprights secured to the innermost plates and having laterally-extending pivotally connected arms at their upper ends, the arm on one Plate crossing-the arm on the other and secured to said first mentioned uprights.
